Embodiment 1
[0031] Embodiment 1 The extraction of sea buckthorn whole fruit oil, refining method 1
[0032] (1) 3Kg of sea buckthorn whole fruit powder after drying, pulverizing, sieving and n-butane are dropped into the extraction tank of subcritical fluid extraction device by the material-to-solute mass volume ratio (g / ml) of 1:5, and the extraction temperature is Continuous extraction at 30°C for 2 times, each time for 40 min, to obtain the extract, which was separated under reduced pressure to obtain the crude oil of sea buckthorn whole fruit. The oil yield was 11.60%.
[0033] (2) the crude sea buckthorn whole fruit oil obtained by extraction is introduced into the hydration tank, stirring and heating makes the oil temperature reach 60 ℃, slowly adding 0.12g 60 ℃ of alkaline water, slowly adding 60g 60 ℃ of water after the phospholipid appears, stop adding water Then, continue stirring for 1 minute and then stop stirring. Drain the oily feet after 8 hours of sedimentation.

Embodiment 2
[0036] The extraction of embodiment 2 whole fruit oil of sea buckthorn, refining method 2
[0037] (1) 3kg of sea buckthorn whole fruit powder after drying, pulverizing, sieving and n-butane are put into the extraction tank of subcritical fluid extraction device by the material-to-solute mass volume ratio (g / ml) of 1:4, at extraction temperature Under the condition of 40°C, continuous extraction was carried out for 3 times for 20 min each time to obtain the extract, which was separated under reduced pressure to obtain the crude oil of sea buckthorn whole fruit, the oil yield was 13.11%, and the extraction yield of this method was calculated to be 82.97%.
[0038] (2) import the crude sea buckthorn whole fruit oil obtained by extraction into the hydration tank, stir and heat to make the oil temperature reach 70°C, slowly add 0.16g 70°C alkaline water, slowly add 110g 70°C water after the phospholipids appear, stop adding water Then, continue stirring for 2 minutes and then stop s...
Embodiment 3
[0041] The extraction of embodiment 3 whole fruit oil of sea buckthorn, refining method 3
[0042] (1) 3Kg of dried, pulverized, sieved sea buckthorn whole fruit powder and n-butane are put into the extraction tank of the subcritical fluid extraction device by the material-to-solute mass volume ratio (g / ml) of 1:3, and at the extraction temperature Under the condition of 45°C, continuous extraction was carried out for 3 times for 30 minutes each time to obtain the extract, which was separated under reduced pressure to obtain the crude oil of sea buckthorn whole fruit. The oil yield was 14.81%.
[0043] (2) the crude sea buckthorn whole fruit oil obtained by extraction is introduced into the hydration tank, stirring and heating makes the oil temperature reach 80 ℃, slowly add the alkaline water of 0.21g 85 ℃, slowly add 150g 85 ℃ water after the phospholipid appears, stop adding water Then, continue stirring for 3 minutes and then stop stirring. Drain the oily feet after 12 ho...
